STEAM-BOILER FURNACE.

Application filed August 3, A1927'. Serial No. 210,346.A

This invention relates to boiler furnaces, whether stationary or portable and burning oil or coal, and aims to conserve fuel: and equalize the heat. if

The invention contemplates an .equalizer arranged in the combustion chamber of the furnace for absorbing heat and distributing the same uniformly and consisting of a php rality of metal bars spaced apart a smalldistance and independently mounted to facilitate repairs vand access to the fire box, or combustion chamber, as required.

While the drawing illustrates a preferred.

embodiment of the invention, it is to be understood that 1n adapting theA means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention ,as claimed, without departing from the spirit thereof. i

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the draw` ing hereto attached, in which,-

Figure l. is a side View 0f a boiler-furnace embodying the invention, a portion of the setting beingl broken away to rshow the relative position of the heat equalizer.

Figur-e 2 is a detail .sectional view of a portion of the boiler on the line 2-2 of Figure l.

Figure 3 is a detail perspective view of one of the bars comprising the equalizer'.

Corresponding and like parts arereferred to in the following description and designated in the several views of the drawingr by like reference characters.

The numeral 1 desi mates the setting of the furnace,y and 9. the boiler, which is of the horizontal flue and tubular type. The numeral 3 designates the front Wall and l the inner or rear wall between which the fire box 5, con Y bustion chamber 6 and ash pit 7, are formed. The front end of the boller Q 1s supported upon the inner or rear wall 4.

The heat equalizer is located within the comlnistion chamber' at or below the bottom 3 and and issupperted thereby. The heat equalizer may be located-any distance above the grate 8. depending` upon the type of the furnace, `whether the same yis designed for burning oil, coal or other f el. The equalizer is of metal so as to absorb and yequalize the heat. ln the preferable construction the heat equalizer is formedof a pluralityof bars 9 disposed in parallel relation and spaced apart short distance. These bars` extend across the con'ibustion chamber and are supported at their ends by the walls 8 and 4. lSimilar metal lplates l() are set intothe walls 3 and i and'receive the ends of the metal bars 9 whichv are .secured thereto by means of bolts 11 or othersuitable fastening;` means. vrllhe bolts or fastenings l1 are passed through registering openings formed in the bars 9 and plates l0. rThe upper portion of the bars 9 beveled to prevent dust, ashes, and other inatter fromlodginu tl ereon and to 'facilitate dissipation of theheat absorbed by the bars. In practice, it has been found that the' heat equalizer absorbs heat and gives the same. in a manner to uniformly dissipate the heat, tb eby resultin in a savino; of fuel and preH ventina the burning and overheating `of the boiler flues and tubes. i

Having thus described the invention.y I claim: i i

The combination with a boiler furnace including' a co .ibustion chamber and fire boi( is oppositely absorber and equaiizer arranged intermediate the fire box aud'comlmstion chamber 'be low the boiler con... i a plurality of between the front and rear walls of tbe furnace and having' their top sides oppositely beveled, and metal plates set in the frontend rear walls of the furnace and receiving,l the ends of the bars which are fasten-ed thereto.

In testimony whereof I affix my signature.
